Period 7,8
1. Effective Collisions – as per the diagram.
 
Every chemical reaction requires collision that are effective = Effective Collisions
 
effective collisions require 2 things:
          1. Energy to overcome repulsive forces of electrons (that are on the outside of the molecules) . ELECTRONS FROM ONE REACTANT REPELS THE ELECTRONS FROM THE OTHER SINCE  ELECTRONS ARE NEGATIVE AND LIKE CHARGES REPEL.
Thus as two reacting molecules start to collide they start to repel until they reach a maximum energy of repulsion = peak energy = Activated Complex.  The energy needed to overcome the activated complex peak is called Activation Energy (Ea).
Every chemical reaction exergonic or endergonic must overcome the energy barrier with Ea.
            2.  Molecules have to collide in areas that can bond and not in area that it cannot.  Thus molecules must collide with the correct orientation ALONG with Ea.
 
1: Light stick Demo – proved the collision theory of molecules.
2.  Nitrogen (l) / balloon  – proved motion of gas molecules
 
3.  Rate of reaction – Rate of metabolism Demo – Radio
 
In all 3 demonstrations Energy is being driven from a system spontaneously by the coupling of a spontaneous process (boiling of the liquid nitrogen) with a non-spontaneous process.
2. Review the Notes with Gummy Bear Demo.
 
Relate it to Biological Metabolism:

Gibbs free Energy and Entropy Notes key – page 6.pdf
The Entropy  ΔSuniverse  is affected by two factors    
There are two ways that energy can be “dispersed” or released.
            1.  Heat or thermal energy is released into the surroundings. ΔH = heat of reaction
                    
                    This thermal energy will increase the temperature of the surroundings and increase the motion of
                    surrounding molecules. This increased motion will make these surrounding molecules “move away”
                    and disperse their motion energy “away” from the system.
                    ΔH = negative if HEAT energy is released – (increases  ΔSuniverse )
                   ΔH = positive if HEAT energy is absorbed – (decreases  ΔSuniverse )
            2.  The degrees of freedom of the particles or molecules increases. ΔS = entropy of particles
 
                   The chemical reaction or physical process increases the number of moving “parts” so that motion
                    energy is dispersed as the chemical or physical process proceeds.
                    ΔS  = positive if degree of freedom increases for molecules as process proceeds.
                   ΔS  =  negative if degree of freedom decreases for molecules as process proceeds.
To measure a if the Entropy ΔSuniverse is decreasing or increasing we use Gibbs Free Energy Formula:
                                                                                            ΔG =  ΔH – TΔS
                         IF ΔG = negative then the Entropy ΔSuniverse  is increasing = Spontaneous
                         IF ΔG = positive  then the Entropy ΔSuniverse  is decreasing = Non – Spontaneous
 
 
2/4 –  Thursday  –  “B” Day  Homework:
 
1. Please view the signs lecture and take notes.
 
 
2. Complete the Thermo signs lecture.
End of Thursday!

2/5 – Friday – “C” Day         – period 7C, 8C -I     7(C) 8(A,C)  AP BIOLOGY – (double period Lab)
                                                    – period 7C, 8C   7(C) 8(A,C)  AP BIOLOGY – REMOTE INSTR
 
The RED Team is REMOTE again &^$(&&(&%%#%#!!!!!
 
1. Reviewed the Always Rule, Never Rule, and Sometimes Rule in the Gibbs Free Energy Equation
2. Review of Gummi Bear demo – without ΔH and ΔS values.
             *Look at the always rule of the combustion reaction of propane (torch). Explain why not all Free Energy is                    transferred from one process to another. This is important in ecology as the producers have the greatest  
              amount of energy in an ecosystem.
 
3.  Review of Cool demo with values.
 
4. Solidification (hand warmer) demo Reviewed.
 
Today’sClass Whiteboard:
 
Cool Reaction:  What is spontaneous and what is non-spontaneous is this demo?

            1.  Heat or thermal energy is released into the surroundings. ΔH = heat of reaction

                    energy is dispersed as the chemical or physical process proceeds.
                    ΔS  = positive if degree of freedom increases for molecules as process proceeds.

                                                                                            ΔG =  ΔH – TΔS
                         IF ΔG = negative then the Entropy ΔSuniverse  is increasing = Spontaneous
                         IF ΔG = positive  then the Entropy ΔSuniverse  is decreasing = Non – Spontaneous
 
Hand warmer demo:  Is this spontaneous? Why must heat be given off in order to for this solution to become a solid?  When has this physical process reached equilibrium?  
Today’s Lesson:
2/5 Friday Homework – 
 
1.  Make another submission to last nights Form -after today’s lesson!
 
2.  Read me!   Look at the 2 reactions below.  The first reaction is the phosphorylation of glucose which is required in the 1st step to get Free Energy out of the glucose. As you can see the first reaction is not spontaneous (ΔG is not negative!) and it is the driven by the second reaction that is spontaneous (ΔG is negative). In this coupled process the the overall ΔG is -17 to show that the spontaneous reaction of ATP was spontaneous enough to DRIVE the first reaction. You may have learned that ATP is the energy currency of the body AND THE reason it is needed by all life sustaining chemical reactions is to COUPLE the endergonic reactions of life that require a steady supply of Free Energy. We will learn that we get ATP from the breakdown of glucose in our body (cellular respiration).
                             
3.  Complete ATP worksheet with textbook (Chapter 8).

 

3. Review with the key – There are mistakes in my key. Question 1 b should have 2 phosphates NOT 3 and 7b should be Exergonic NOT Endergonic! I feel bad and I am over it.
